more easterly component across those metro terminals tomorrow
afternoon. Should likely see another around of diurnal cu tomorrow
afternoon, but anticipated to hold at VFR heights.

DISCUSSION...

Moist ambient conditions due to shallow cold advection, nocturnal
cooling, and recent rainfall led to stubborn low cloud and br early
today. Main item for note in the near term is the near surface cold
front that is currently working southward. Increasing anticyclonic
flow trajectories aided by colder air streaming southward down the
long axes of the Great Lakes will help sweep or backdoor the
synoptic front to the Ohio border by 03z this evening. Outside of a
slight chance for a rogue shower or thunderstorm this evening,
conditions will be pleasant with temperatures dropping down into the
70s by 9-10pm.

Strong, compact surface ridging will expand over Southeast Michigan
tonight and linger over the region through at least early Saturday.
Just a glancing shot of low level cold advection will allow the warm
temperatures to lift back into the state quickly during the end of
the week.  Highs in the lower 80s Thursday will give way to 90
degrees again by Saturday. The one note is that surface dewpoints
should hold in the 60s the next few days.

The next chance for precipitation across Southeast Michigan should
largely hold off until late Saturday and Sunday. A midlevel trough
over northern canada should suppress heights enough to introduce a
weak upper level jet axis over the Great lakes. The return of the
kinematics could allow for an MCS or two to approach the area from
northern Wisconsin and the U.P.  The going forecast has chance PoPs
in the forecast for Sunday.

MARINE...

Sprawling high pressure over Ontario will promote northerly winds
over the Central Great Lakes into tomorrow. Despite the onshore flow
developing over southern Lake Huron, with wind speeds mostly at 15
knots or less, waves are expected to hold below 4 feet, and no small
craft advisory is planned.

Return flow around departing high pressure will allow winds to flip
around to the south by Friday, but winds still look to be generally
light (under 20 knots) into Saturday. The forecast becomes muddled
on Sunday as a cold front drops south through the Central Great
Lakes. It`s possible front will speed south, with enough of a
gradient to support north-northeast winds in excess of 20 knots over
Lake Huron by Sunday afternoon. However, confidence is a bit low, as
convection/thunderstorms may be around into early next week, which
will also tend disrupt/impact the wind fields.
